MOLD..

Specification of Letters Patent.

Patented Oct. 16, 1917.

Application filed November 15, 1916. Serial No. 131,534.

To all whom it may concern:

Be it known that I, MERCY E. BAKER, a citizen of the United States, residing at Westport Point, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Molds, of which the following is a specification.

This invention relates to molds and more particularly to a spherical-shaped mold for receiving and compressing paper pulp or the like whereby compressed spherical units may be formed for utilizing paper as a fuel.

One of the objects of the invention is to provide two cooperating hemispherical members having means whereby they may be manually pressed into engagement with each other for compressing a fibrous or pulpous mass into a compact unit, the hemispherical members being provided with a plurality of apertures whereby the moisture may be excluded from the mass while the same is being compressed.

A further object of this invention is the provision of a mold which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following descripand the accompanying drawings, wherein is illustrated the preferred form of my invention, in which;

Figure 1 is a top plan.

Fig. 2 is a section on the 2-2 of Fig. 1.

It has been demonstrated that old newspapers or other .similar waste paper may be utilized for fuel for heating or cooking purposes by first soaking the waste paper in water and then compressing portions of the pulpous mass thus formed until the moisture is excluded. In order that the mass may be thoroughly compressed and freed, from moisture, at the same time formed into a unit of uniform configuration, the device herein described is constructed to form the mass into a compact sphere. Therefore, I have provided two hemispherical portions 1 and 2 which constitute the main portion of the mold. For the purposes of this description the halves of the mold are designated as the upper mold 2 and the lower mold 1. The peripheral edge of the lower mold 1 is provided with an annular groove 3 and the outer wall of the groove thereby forms the annular flange 4t extending completely around the proximate edge of the lower mold 1.

The proximate edge of the upper mold 2 is adapted to fit within the annular groove 3 when the upper and lower molds are in closed position. It is to be observed that the proximate edges of the upper and lower molds are extended slightly beyond the diametrical center line of its respective mold thus permitting the edges to overlap 'as' clearly shown by Fig. 2 of the drawing. By virtue of the edge of the upper mold fitting in the annulargroove 3,'a perfectly spherical interior is provided thus assuring a per-' fectly spherical and compact unit.

Projecting from the edge of the lower mold 2 is a pair of cars 5 having apertures formed therein while the upper mold is provided with a lug or ear 6 adapted to be disposed between the lugs 5 and has the central opening arranged in alinement with the openin 's in the ears 5. A hinged pin or pintle 4 is projected through the openings 7 thereby providing a hinge for opening and closing the mold.

At the opposite edge of each mold is a handle 8 and it will be noted that the handle of the upper mold is adapted to extend into a notch 9 formed in the annular flange 4 of the lower mold thereby permitting the handles to be moved into close relation when compressing the mold. As shown by Fig. 1 of the drawing the handles 8 are spaced apart with respect to their lateral disposition thereby permitting the handles to move into closer relationship for closing the upper and lower molds together as clearly shown by Fig. 2 of the drawing. Each element of the mold is provided with a plurality of openings 10 for permitting the water and moisture to escape from the pulpous mass when the same is being compressed.

It .is pointed out that the formation of a spherical inflammable unit for fuel purposes will, by virtue of its spherical formation, burn evenly and uniformly thereby resulting in the maximum heat beng obtained when a number of the units are being consumed. Furthermore the formation of a spherical unit from a pulpous watery mass will be more readily drained of water and moisture than would a unit of any other f rmation From the foregoing it will be observed that a very simple and durable mold has been provided, the details of which embody the preferred form. I desire it to be understood however, that slight changes in the minor details of construction may be made without departing from the spirit of the invention or the scope of the claims hereunto appended.

I claim:

1. A mold comprising a hollow body divided into two hemispherical mold sections, each being perforated with a plurality of openings, the marginal edges of each of the sections being adapted to contact for tightly closing the interior of the hollow body for forming a perfectly spherical mold chamber, the marginal edge of one of the sections having an annular flange adapted to embrace the marginal edge of the correspond ing section on the exterior thereof, handles carried by each of the sections, the said flanges being adapted to move toward or away from each other, the said flange having a notch provided in the path of movement of one of the handles whereby they may be moved into close proximity for 010s ing the said sections,-and hinges connecting the said sections.

2. A mold comprising a body divided into upper and lower hemispherical mold portions, the edge of one of the mold portions being provided with an annular groove, the outer wall of the groove forming a flange on the edge of the said mold portion, the

edge of the corresponding portion being adapted to fit within the said groove for providing a perfectly spherical interior when the said mold portions are moved into engagement with each other, handles carried by each of the portions, and adapted to move into close relation for closing the said mold, the said flange having a notch for receiving one of the said handles. 7

In testimony whereof I affix my signature in presence of two witnesses.
